Besides alarming loss-of-synchronization, there are various warning signals depending on the alarm
issued. Also, Ezi-STEP provides an easy interface to communicate with an upper controller by issuing
RUN/STOP signal.
(The type of alarm issued can be identified by LED indicator)

Depending on the speed of a stepping motor, Ezi-STEP automatically increases the supply voltage and
prevents the torque lowering due to the low effective operating voltage on a motor from the back emf
voltage, in turn enabling a high-speed operation. Also, the software damping algorithm minimizes the
vibration and prevents the loss-of-synchronization at high-speed.
